Title:
DYNAMO-ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/154287
Kind Code:
A1
Abstract:
A dynamo-electric machine, wherein slots are provided between the teeth of a stator core. The ratio of the number of poles and the number of slots is 2:3. The tooth tip width, which is the width dimension of the tip of the teeth in the circumferential direction of the stator, is within a range of the electrical angle ±0.2° × P with respect to a value that satisfies β = –2.5 α + 319.7 (0 <β ≤ 180) [deg], where α is the electrical angle of the tooth tip width, β is the electrical angle of the pole arc angle, which is the angle formed by two straight lines that connect the rotation center of the rotor to the corners on the rotor surface-side of one permanent magnet, and P is the number of pole pairs.
